Solution :

Angular momentum of electron (L)=nh2π(L)=nh2π

Magnetic moment of electron M=n×BohrM=n×Bohr

=n[eh4πm]=n[eh4πm]

gyromagnetic ratio =magnetic momentangular momentum =magnetic momentangular momentum 

=neh/4πmhh/2π=neh/4πmhh/2π

=e2m=e2m

=constant=constant

It is independent of the orbit it is in

Since e is negative , the geomagnetic ratio is negative.

Answer :Negative
